link(pid)

what about process linking?

You can propose how to do it

Unfortunately I am new in golang)
Тake a look at the implementation of Jinterface. We can see simple construction in OtpMBox.java. There are two ways. Local and external:

    public void link(final OtpErlangPid to) throws OtpErlangExit {
    try {
        final String node = to.node();
        if (node.equals(home.node())) {
*on the same node:*
        if (!home.deliver(new OtpMsg(OtpMsg.linkTag, self, to))) {
            throw new OtpErlangExit("noproc", to);
        }
        } else {
*on the external node:*
        final OtpCookedConnection conn = home.getConnection(node);
        if (conn != null) {
            conn.link(self, to);
        } else {
            throw new OtpErlangExit("noproc", to);
        }
        }
    } catch (final OtpErlangExit e) {
        throw e;
    } catch (final Exception e) {
    }

    links.addLink(self, to);
    }

The last link in the chain is sendLink method in AbstractConnection.java

protected void sendLink(final OtpErlangPid from, final OtpErlangPid dest)
        throws IOException {
    if (!connected) {
        throw new IOException("Not connected");
    }
    final OtpOutputStream header = new OtpOutputStream(headerLen);

    // preamble: 4 byte length + "passthrough" tag
    header.write4BE(0); // reserve space for length
    header.write1(passThrough);
    header.write1(version);

    // header
    header.write_tuple_head(3);
    header.write_long(linkTag);
    header.write_any(from);
    header.write_any(dest);

    // fix up length in preamble
    header.poke4BE(0, header.size() - 4);

    do_send(header);
    }
